I agree that we should invest in mental health awareness and free treatment; although a ban on gun may seem attractive at first, I don't think 2013 or anytime in the near future is a good time to do it. There's too many people that already have guns, and having a gun ban, even without dealing with plausible riots and the black market, might be more expensive than we can handle. After all, how are we going to ensure that nobody has a gun after the ban is implemented? If it's knocking at their front door, I don't think it's going to work out very well.
